For this case what you should do is evaluate values of x in the function and verify that they meet the result of f (x) shown in the graph.
 The answer is
 f (x) = - 2lxl +1
 notice that
 f (1) = - 2l1l + 1 = -1
 f (-1) = - 2l-1l + 1 = -1
 Both comply with the value of f (x) shown in the graph
 answer
 f (x) = - 2lxl +1

Hi there!

\large\boxed{\frac{1}{4}, -\frac{3}{2}}

13y² + 10y - 3 = 5y²

Begin by moving all terms to one side:

13y² + 10y - 3 - 5y² = 0

Combine like terms:

8y² + 10y - 3 = 0

Factor using the guess-and-check method.

(4y - 1)(2y + 3) = 0

Set each factor equal to 0 to find the solutions:

4y - 1 = 0

4y = 1

y = 1/4

2y + 3 = 0

2y = -3

y = -3/2

Burka [1]
There would be 3 triangles formed.
Each interior angle of a triangle will sum up to 180 degrees.

The 1st triangle will have 130,25, and 25 as its angle measures.

The angle 130 degrees will be divided into 2 to create 2 right triangle. Each triangle will have angle measurements of 25, 65, and 90 degrees.
